1 b aZZ whom it may concern:

Be it known that I, FREDERICK H FERR a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Insole-Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to machines for operating on soles and moreparticularly to the performance of certain operations upon insoles.

In the manufacture of certain types ofinsoles it is desirable to performan operation- The present invention-relates to machines of the type andfor the purposes just set forth, and one object of the invention is toproduce a machine of simple construction and compact form, andparticularly a machine in which the actuating mechanisms are of a simpleand direct character and are located for the most part, below and in therear of the work-support upon which the insole rests during theoperation thereon.

Another object of the invention, relating particularly to its use inconnection with reinforced soles, is to provide simple and effectivemeans for trimming the reinforcing material. In order to prevent thereinforcing material on a Gem insole from being visible in the finishedshoe, it is desirable to trim the material, particularly at theshank-portion of the insole, to a line on the feather within the edge ofthe insole. In

Specification of Letters Patent.

Such w Patented Nov. 19, 1918.

Serial No. 154,187.

the machine of the present invention it is proposed to employreciprocating work-en: gaging members for feeding the Workintermittently, and to provide a trimming cutter for the reinforcingmaterial which is so mounted as to reciprocate With the feedinginstrumentalities. From this arrangement it results that the cuttermoves with the work during the feeding movement, while its operation isperformed during the return movement of the feeding instrumentalitiesand while the work is held stationary by means provided for thatpurpose- Consequently, although the cutter operates with a draggingaction, it does not impede the intermittent feeding movement, since itsoperation is timed to alternate with the feeding movement.

Other objects of the invention, the advantages of which will be readilyrecognized by those skilled in the art, will be set forth in connectionwith the description of the preferred embodiment of the invention.

To the accomplishment of the above objects the invention comprises thefeatures and combination of parts hereinafter described and defined inthe appended claims.

The preferred embodiment of the invention is illustratedin theaccompanying drawings in which Figure 1 is a side elevation,

, partly in vertical section; Fig. 2 is a partial side elevation showingcertain of the operative instrumentalities in a position other than thatshown in Fig. 1; Fig. 3 is a plan view of the machine; and Fig. 4 is adetail view, in section, on the line 4:& of Fig. l.

The invention is illustrated as embodied in a machine adaptedparticularly for ribtightening or perfecting reinforced insoles of theGem type, theperfecting operation herein consisting in. pressing thereinforcing material. usually canvas or duck, firmly into the anglesbetween the rib and thebody and feather of the insole, and in bendingthe rib to, and setting it in, an inwardly inclined position.

As shown in Figs. 1 and 3, the insole upon which the machine operatescomprises the usual body-portion 6, having a rib produced by an integralupturned lip 8 and a marginal feather 10. This insole is rein forced bycanvas 12, which is connected in place and extends over the 11p and theadjacent surfaces of the body and the feather,

The instrumentalities of the machine 1nclude a work-support 14:, 1n theform of a disk, with av horizontal flat surface uponwhich the insolerests. This disk is fixed on the upper end of a stem 16 which slidesvertically, and rotates, in a stationary sleeve 18. This sleeve isintegral with a housingmember 20, which serves as a frame and alsoaninclosurefor the actuating mechanism of the machine, being mounted atthe upper end of a column'22 of convenient form and height.

The work support is pressed upwardly by a spring 24 which is coiledwithin the sleeve 18 and around a rod 26. The rod is concentric with,and fixed to, the stem 16, and it slides through a centrally perforatedstop-screw 30 which is threaded into the sleeve 18. The rod is providedwith adjustable stop-nuts 28 which cooperate with the screw '30 to limitthe upward movement of the work-support under the influence of thespring,when no work is in the machine. To facilitate the introduction ofan insole the rod 26 may be connected with operating means such-as atreadle (not shown) by which the work-support may be depressed in theusual manner.

The lip-forming tools comprise a member 32 which engages theinnersurface of the lip and acts as an anvil, and a member 34 which engagesthe outer surface of the lip and acts as a hammer by which the lip isbent and compressed against the anvil. It will be observed from Fig. 2that when the lip is pressed between the lip engaging faces of the twotools 82 and 36 it is bent to an inwardly-inclined position the pressureextending from the base to the crown and being suflicient to set the lipin this position.

For the purpose of trimming the margin of the reinforcing canvas 12 themachine is provided with a knife 36.

The anvil 32 and the hammer 84 are employed as means for feeding thework inter mittently, and for this purpose they are so mounted as toswing about a vertical axis in the rear of the work-support. A] :arriage 38 is mounted within an upper housing-member 4-2 which isremovably fixed upon the lower housing-member 20. The carriage isprovided with a horizontal circular flange 40 which rests upon the uppersurface of the housing-member 20 and fits in a correspondingly formedopening in the member 42, so that a bearing is provided on which thecarriage may be oscillated about the axis of the flange 40. The carriageis held down against the bearing just described by engagement with theupper part of the housing-member 42. as shown in dotted lines in Fig.1', and'it is'centercd. at.

its upper end, by means of a pivot-stud 44 fixed in the houslng andentering a recess in the top of the carriage.

The hammer is mounted upon a slide 46 which moves in a circularly curvedguideway 47 formed in the carriage 38'. The center of the curvature ofthis guideway is located below, and slightly in the rear of, theWork-support, so that when the hammer is actuated by the movement of theslide in the guideway its operative extremity moves toward and from thelip of the insole in a path which is slightly inclined in a forward anddownward direction. When the carriage is oscillated about its verticalaxis the hammer is reciproc-ated, through a short arc, about such axisfor the purpose of imparting a feed-movement to the insole through theengagement of the hammer with the lip of the insole. In order that itmay participate in the same function. the anvil is mounted in a forwardprojection from the carriage, as will be described.

For the purpose of actuating the slide 46 and the hammer, the lower endof the slide is connected, by a ball-and-socket joint 48. with aneccentric-strap 50- which embraces an eccentric 52. This eccentricisactuatedby a power-shaft 53, and theshaft is journaled in bearings inthe lower housingmember 20, and provided with a pulley 56 through whichit may be connected with any suitable source of power. By these means aconstant and rapid reciprocation of slight amplitude is imparted to theslide and the hammer, causing the latter to move into and out ofengagement withthe lip of the insole. In order to provide for operatingupon insoles having lips of ditfercnt thicknesses, the hammer isadjustahly connected with the slide by means of a bindingscrew 58, whichis threaded in. the slide and passes through an elongated opening invthe shank of the hammer, and this shank is seated in a close-fittingrecess in the slide.

this recess being concentric with the slide so as to limit the adjustingmovement to a circularly-curved slide.

The lip-forming tool 32 has a cylindrical shank 60 which slidesvertically in a sleeve 62, and this sleeve is integral with a forvwardprojection from the carriage so that the oscillating movements of thelatter cause the tool 32, to participate in the workfeeding movement ofthe hammer. The tool 32 is supported rigidly. by the sleeve against thepressure due to the impact of the hammer, but by vertical moirment ofthe shank in. the sleeve the tool is permitted to accommodate itself toinsoles of various thicknesses. v

During the lip-forming and feeding op erations the tool 32 is forceddownwardly against the .work by spring pressure, as

path concentric with the shown in Fig. 1. For this purpose a leaf spring64: is employed, this spring being articulated, at its forward end, tothe shank 60, while its rear end is fixed to a lever 66 which is mountedon a pivot 68 on the car-- me e.

uring the idle return movement of the tools following each feed movementthe pres sure of the tool 32 against the insole, as shown in Fig. 2,pose the lever 66 is connected, by a link 70, with a pivot-screw 72 onthe slide 46. so that at each retractinzr movement of the slide and thehammer the ever is rocked in a direction to release the tension of theSpring 64. In order to insure the entire release of the pressure of thetool against the insole the lever is provided with a forwardly-extendingarm 74 of which the end comes into engagement with the lower surface ofthe spring when the lever is moved to its extreme position, and thus,through the intermediation of the spring, the tool 32 is lifted a shortdistance clear of the work. This distance is, or may be, so slight,however, as not to be distinguishable in the drawings, a lift of a smallpart of an inch being suflicient to in surethe release of the Work fromcomp-ression.

When the hammer is retracted and the anvil is raised, as just described,it is necessary to prevent the insole from being forced upwardly by thespring 24 of the work support. and also to retain theinsole securely inposition during the return movement of the tools. For this purpose apresser-foot 76 is employed. This presser-foot is pivoted. by a stud 78, on a bracket 80 which is fixed in stationary position on the housing.Integral with the presser-foot is a depending arm 82 which carries aroller 84;. The roller cooperates with a cam 86 fixed on the powershaftand is maintained in engagement therewith by a spring 88 attached to thearm 82. The cam is formed to permit the spring to swing the armrearwardly, and thus depress the presser-foot to operative engagementwith the feather of the insole. at the completion of each lipforming andfeeding operation. and the presser-foot remains so depressed until thelip-forming tools have completed their return movement and again engagedand gripped the work. whereupon the cam 86 acts to swing thepresser-foot upwardly. out of engagement with the work. so as to permitthe latter to be fed freely.

The canvas-trimming cutter 36 is mounted adjustably upon the carriage byits dove-tail shank. which is fixed in vertical position. by

means of a clamp-plate 90 and a screw 92,

against a bracket 94L which is fixed, in turn,

by means of a screw 95. to the forward portion of the carriage 38. Thecutter may be adjusted vertically upon loosening the screw '92, so as toset it to out only to the required is released. For this purdepth tocompletely sever the canvas with out mutilating the feather. The bracket94 has a horizontal .rib-and-groove connection with the carriage, asshown in Fig. 4, so that it may be adjusted'forwardly and rearwardlythereon to decrease or increase the distance of the knife from the lip.Such an adjustment will vary the distance of the cut from the edge ofthe insole, itbeing remembered that the insole is guided by its ribwhich lies at varying distances from the idge of the insole. The knifeis preferably set so as to engage the canvas at a distance,

from the lip, approximately equal to the width of the narrower portionsof the feather, so that at the shank portion of the insole. where thefeather is widest, the cut will comewell within the edge. thus insuringthat the canvas shall not'be visible in the finished. shoe. lVith suchan adjustment of the parts it will be observed that in case the canvasalready has been trimmed flush with the insole edge when the insole isbrought to the present machine, the knife 36 performs its function onlyat the shank.

Owing to the fact that the trimming cutter is mounted on the carriage;it oscillates with the lip forming and insole feeding tools. andconsequently its cutting operation is performed during the returnmovement of the latter. Accordingly, the drag of the knife upon the workoccurs while the work is held stationary. between the work-support andthe presser foot, and this arrangement has the advantage that theoperation of the knife does not resist the intermittent feed movement ofthe insole. Furthermore, the cutting edge of the knife being directedaway from the presser-foot provides for a clean severance, that is,there is no opportunity for the fabric to buckle as would be the case ifthe cutting stroke, were toward the point where the insole is clamped.

The oscillatory feeding movement of the carriage is produced by cammechanism. For this purpose a block 96 is pivoted to the bottom of theflange 4:0, and is embraced by a forked cam lever98 which rocks upon apivot-stud 100 in the housing of the machine. as shown in dotted linesin Fig. 3. The cam levercarries a roller 102 which en gages a cam 10%fixed on the power-shaft At each rotation of the shaft, accordingly. thecarriage is swung once in each direction to produce a feed movement ateach cycle of operations.
